BURTON A. BAUS, OF GLOVERSVILLE, NEW YORK.

SELF-'DUIVIPING BUCKET.

Specification of Letters Patent.

Patented June 11,1907.

Application filed April 9,1907. Serial No- 367,260.

To all whom it may concern:

Be it known that I, BURTON A. BAUS, a citizen of the United States, residing at Gloversville, county of Fulton, and State of New York, have invented certain new and useful Improvements in Self-Dumping Buckets, of which the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described an d subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a view in perspective of my improved self-dumping bucket as the same appears in carrying a load. Fig. 2 is a similar view of the bucket in dumping position.

The principal object of the invention is to provide automaticallygreleasing supporting connections for a dumping-bucket.

Other objects of the invention will appear in connection with the following description.

Referring to the drawings wherein the invention is shown in preferred form, 1, represents the bucket, to opposite sides of the forward portion of which are connected the bail-chains, 2, which converge to a ring, 3, connected with a chain, 4, passin over the K chain, 7, connects the pulley-block, 6, directly with the rear end of the bucket at S. The chain, 7, is provided intermediately of its ends with a ring, 9, ada ted to receive a self-releasing hook, 10, on t 1e end of chain 4. Thepulleyblock, 6, is attached to the lower end of the hoisting-rope 12. The chains, 2, are provided with a spreader, 13, which may be omitted if desired.

The chains, 2, are so connected with the front end of the bucket that the center of the load is necessarily in rear of said points of connection. When it is desired to transport the loaded bucket, the hook, 10, is connected with the ring, 9, leaving the portion of the chain, 7, between the pulley-block and said ring, 9, slightly slack, the parts being in the position shown in Fig. 1. The load, being in rear of the points of connection of the chains, 2, with the bucket, tends to tip the bucket rearwardly'iuitil such tipping movement is arrested by engagement of the ring, 3, with the pulley-block 6. When it is desired to dump the load the bucket is lowered upon the. ground, or other suitable support, until the bail-chains become sufficiently slack to permit the hook, 10, to drop out of engagement with the ring 9. The pulley-block is then again lifted by means of the hoisting rope, causing the slack in the chain, 7, to be immediately taken up, and the lifting-pull to be exerted directly upon the rear end of the bucket, while no pull is exerted upon the front end of the bucket until the slack in the chains, 2, 3 and 4, has been taken up and the hook, 10, brought into engagement with the pulley-block, 6, as shown in Fig. 2. The bucket is thus caused to tip to the proper dumping angle.

The ring, 3, and the hook, 10, are made of sufficient size to prevent their passage through the pulleyblock so that they form stops to arrest the movement of the chain, 4, in opposite directions through the pulleyblock for the purposes above explained.

Any other known form of stop may be attached to the chain, 4, to engage the pulleyblock in place of the ring, 3, or hook 10.

The hook, 10, may be any known form of open hook, but to facilitate the automatic release of the hook from the ring, 9, I prefer to provide the hook with an over balanced arm, 14, as shown, whereby as soon as the pull upon the chain, 4, has been relieved the weight of the arm, 14, will tend to invert and release the hook.

The bucket may be of any known form.

What I claim as new and desire to secure by Letters Patent is 1. The combination with a dumpingbucket; and a hoisting pulley-block and pulley; of a chain connecting said pulley-block with the rear end of said bucket; an automatically releasing hook adapted to connect with an intermediate portion of said chain; and a chain-connection between the front end of said bucket and said hook passing over said pulley.

2. The combination with a dumpingbucket; and a hoisting pulley-block and pulley; of a chain connecting said pulley-block with the rear end of said bucket an automatically releasing hook adapted to connect with an intermediate portion of said chain; and a chain-connection between the front end of said bucket and said hook passing over said pulley, and having stops adapted to engage the opposite sides of the pulleyblock whereby the movement of said chainconnection is limited.

3. The combination with a dumpingbucket; and a hoisting pulley -block and pulley; of a chain connecting said pulley-block with the rear end of said bucket; an automatically releasing hook adapted to connect with an intermediate portion of said chain; a pair of chains connecting the front end of said bucket with a common ring and a chain passing over said pulley and connected at one end to said ring and at the other end to said hook.

4. The combination with a dumpingbucket; and a hoisting pul1ey-block and pulley; of a chain connecting said pulley-block with the rear end of said bucket; a hookmember havingon one end an open hook adapted to engage an intermediate portion of said chain, and its other end over balanced and a chain-connection between an intermediate portion of said hook-member and the front end of said bucket passing over said pulley. t

In testimony whereof, I have hereunto set my hand this first day of April, 1907.

BURTON A. BAUS.
